Version: 1.2 (using KDE KDE 3.1.3) Installed from: RedHat RPMs Compiler: GCC 3.3.2 OS: Linux I imported some .h files. I saw my class had the 4 operator++/-- methods called ++ and --. I noticed that the postfix ++/-- had parameters defined with no names (makes sense, I did not name them) - however I cannot DO that myself without importing. So I deleted them (all 4) and recreated them by doing operator-- and defining param type/name as: int/postfix, returning SequenceId&. Then I tried making an operator-- with no params and returning SequenceId&. When hit ok the app crashes (Backtrace below) After narrowing the bug to this reproducible error, I rebuilt the bin using debug and ran it in gdb. Got the error, traced the backtrace and saw the UMLXI...? pointer last args was set to 0. This was seemingly done about 3 calls up the stack. I know nothing about the app, so rather than taking days to look into this, I am posting the report before then ;) I read this bug was fixed in 1.2. I am running an "up to date" version of RH9 (ie: rhn updates) with compilation done with a source compiled GCC-3.3.2. The version of KDE is the "stock" (updates applied) 3.1-12 from RH9. (I did not see this version listed on your site) and I downloaded the "new" Umbrello 1.2 source dist on the umbrello site. No special compile options given. (is there an "integrator" to the KDE/Gnome RH desktop menus? I had to "manually" insert the links and not sure I did it right, however it runs from the app shortcut and bin directory (/usr/local/kde/bin which is separate from the RH installs (I linked the individual files (ln -s) to the RH locations so all are there...))
